LOS ANGELES, (Reuters) - Los Angeles police  investigating Michael Jackson’s sudden death said yesterday  they do not consider his doctor a suspect despite having  questioned him about his presence at the time of the pop idol’s  fatal cardiac arrest.

The Jackson family had yet to announce funeral arrangements  for the 50-year-old King of Pop. But a family friend told  Reuters that a service could be held on Wednesday and that the  family wanted to bury Jackson at his famous Neverland Ranch.

The death of one of the most gifted musical performers of  his generation prompted tributes and condolences, from U.S.  President Barack Obama to legions of fans in Hollywood. Top  performers were set to honor Jackson at the BET Awards in Los  Angeles on Sunday.

It was still unclear what, if any, role Jackson’s  prescription medicines might have played in his sudden death on  Thursday. The family carried out its own autopsy on Saturday  after the Los Angeles Coroner said it would need four to six  more weeks to determine the exact cause of death.

Late on Saturday, police interviewed cardiologist Dr.  Conrad Murray in a second meeting that lasted three hours. The  doctor was hired ahead of Jackson’s comeback concert series in  London this month. “He was interviewed as a person of interest, not a  suspect,” Officer Norma Eisenman, a Los Angeles Police  spokeswoman, told Reuters.

A police statement added that “Dr. Murray was cooperative  and provided information that will aid the investigation.”

According to media reports and a family friend, Jackson was  injected with the narcotic painkiller Demerol before he went  into cardiac arrest, and Murray was trying to revive him when  paramedics arrived.
